Every time I press Shift+Ctrl+W to export my file it shows "An Unknown error occurred" in preview section and it is not file specific it is occurring since yesterday night I using Windows 10 Pro and Photoshop version 184.108.40.206
I can't export a certain group from a Photoshop file. It's just this one group, and duplicating it or putting it into a new .psd file does not help. This has been happening since version 22 released.
What are you doing with your apps, Adobe? All these updates and they fix nothing.
Putting the layers into a new group solved it for me. Ugh.
It seems to happen with larger files, or even not-so-large files, if you scale them in the export window.
It's sort of ridiculous to me that this is still happening. This also would be an excellent opportunity to automate this sort of thing with Actions, but alas, that's not supported!
The fix for me was to create a new artboard, and then drag all the layers from the non-exporting artboard to the new one.
I was having the same problem and i tried everything everything in this chat was saying to do and nothing was working, untill i tried flattening the layers, then everything exported perfectly lol
Hey! So I just ran into this issue myself, The cure for me was Edit/Purge/All
Just clearing the scratch disks solved this for me! I hope this helped
Purge/All doesn't work for me at all – I tried it several times.
As for the supposed fix, this issue is still happening in version 22.4.2.
Over a year later from the first post, and the issue is still occurring. I just updated to 22.5 and I'm getting the "an unknown error occured".
I've been using 22.5.1 for several weeks and I just started having this issue. One thing I am noticing is that it seems to happen with larger PSD files. For example, the one I've been using is about 1.4GB, but when I rasterize all of my layers it drops down to 20MB and i don't have the export error. I've also opened several other files that are way lighter as a test and they all exported fine too. Maybe check your file sizes and maybe together we can narrow it down to a certain size causing the problem.
As a side note, I plan to do another test by saving all of my layers (non-rasterized) to linked smart objects to see if I an reduce the file size but still use the full sized layers. I just want to make sure it's not a problem with the objects on my layers instead of just a file size issue.
To follow up....I tried saving my files to linked smart objects and it did reduce the file size (19MB), but it did not solve the export error issue, so it must be more than just file size. For now I'm going to rasterize my layers, then export, then undo the rasterization. It'll be faster than exporting one artboard at a time.
If you stamp all your layers (Ctrl/Cmd + Alt/Opt + Shift + E), then try to export, does the problem still occur? I'm just curious. (Be sure to target the topmost layer first; it always puts the stamped image above where you've selected in the Layers panel.)
